BURNER.

Specification of Letters Patent. i Patented May 13, 1919.

Application filed August 7, 1918. Serial as. 248,665

To all wkomz't may concern:

Be it known that we, JOSEPH ROI-IR and FRED KURzRooK, subjects of the German Emperor, residing at Brooklyn and Canarsie, New York, have invented certain new and useful Improvements in Burners, of which the following is a specification.

Our invention relates to a hydrocarbon burner, of thetype in which gas is generated from oil, and such gas admixed with steam to form the fuel.

The principal object of the invention is to provide a burner of simple construction, capable of developing an intensely hot flame at a minimum cost of fuel.

Another object of the invention is to provide a simple form of valve wherein the admixture of the constituents of the fuel is efi ected, and their proportions may be readily adjusted. i

The invention will be fully hereinafter described with reference to the accompanying drawing, in whicha 1 Figure 1 is an elevational view, partly in section, of our improved burner;

Fig. 2 is a plan view of the oil pipe, surrounding the burner casing which latter appears in horizontal section; and

Fig. 3 is a sectional view of the mixing and controlling valve for the fuel.

The construction herein contemplated is one in which a liquid hydrocarbon, such as kerosene, is caused to flow through a pipe in a heated zone, whereby the oil is gasified, and the gas thus generated flows to and through a valve wherein it admixes with superheated steam generated from water supplied to a casing or receptacle in such heated zone.

Referring to the drawing, 10 denotes a tank which may be supplied with any suitable hydrocarbon such as kerosene. The tank 10 may be placed outdoors or underground as found most convenient, and is connected by'a pipe 11 with any suitable source of pressure, such as a compressed air pump (not shown), to force the liquid out of the tank 10. A pressure gage 12 is preferably arranged on the dome of the tank 10.

Extending to near the bottom of the tank 10 is an oil feed pipe 13, which passes upwardly from the tank 10, encircles the burner casing 14 as at 13*, and then has a downward branch 13 and a horizontal branch 13 which leads to the mixin valve Y, Suspended on the horizontalranch,

"spectively.

13 is apan 15 into which a small quantity of oil may be poured and ignitedto start the burner in operation.

The burner 14 may consist of an ordinary cylindricalcasing provided with flame-outlet orifices l4 near its upper edge, in line with the encircling portion, 13, of the oil feed pipe.

Superimposed on the burner casing 14 is a water receptacle or boiler 16, to which water is fed through the pipe 17 from any suitable source (not shown). Leadingout of the boilerl6 through the head thereof is a steam pipe 18 which opens into one of the branches of the valve Y.

The valve Y comprises an integral casting having the oppositely extending nipples 19 and 20 for the connection thereto of the emission ends of the pipes 13 and 18, re The nipples 19 and 20 are pro vided with the axial bores or ducts 21 and 22 which extend toward the center of the valve but do not meet. The head of the valve is denoted23, and is hollowed out to form a substantially conical seat for a correspondingly shaped plug 24 having a conically pointed head 24 The plug is held in position by a cap 25 threaded to the head 23 and engaging a shoulder 26 formed on the plug intermediate its ends.

The plug 25 is provided with an axial duct 1 27, and near its lower end with a transverse chamber 28. Leading at rightangles from the duct 22 into the duct 27 is a branch duct 22 and leading at anobtuse angle from the duct 21 into the chamber 28 is a branch duct 21 The flow through ducts 21-21 and 22--22 is controlled by valve mechanism constructed as follows z-Projecting rearwardly from the casting Y in line with the duct 22 is a valve socket 29 in a bore of which is 'mounted the partially threaded valve stem 30 provided with the hand wheel 31 for moving the stem. Projecting at an angle'from the casting Y in line with the duct 21 is a second valve socket 32 in a bore of which is mounted the partially threaded valve stem 33 provided with the hand wheel 34, Suitable packin glands 35 are threaded into each of the soc ets 29 and 32 to prevent leakage past the valve stems 30 and 33.

Connected to a nipple 14 in the base of the burner casing 14 is a.pipe 36 having a flaring end 36 into whichthe head 24 of the plug 24 projects. The pipe 36 extends from the valve Y to the burner casing 14: and the fuel mixture passes therethrough from the former to the latter.

The burner operates as follows :P'ressure is admitted to the tank 10 through the pipe 11', forcing oilupwardly through the pipe 13. A. small quantity of oil is poured into the pan 15 and ignited whereby the oil flowing. through the branch: 13 is converted into gas,v Water is then admitted through the pipe 17 into the boiler 16-. When the pipe branch 13 has been sufficiently heated, which occurs in a very short space of time, gas will flow through the ducts. 22, 22 and 27, through: the pipe 36 and into the burner casing 14, where the gas is ignited. There'- upon the flames-issue through the orifices 14 against the. circular portion 13 of the oil feed pipe gasifying all the oil flowing therethrough from the tank 10. The heatof the burner. 1i alsoconverts the water in the tank 16 into steam. There isthen a constant generation of gas and steam, the gas flowing, as before described, through pipes 13 and 13 into the valve and the chamber 28, and the steam flowing through the pipe 18 into the valve through the ducts 21, 21 and into thechamber 28.. 'llhelatter may be properly termed a mixing; chamber, as the gas and steam commingle therein and the mixture flows out through the upper part. of duct 27 through the-pipe 36 and into the burner casingv 1-4:.

The: proportions of gas and steam may be readily controlled by suitably manipulating' the valve stems 30 and: 33.. An up or down movement of the stem 30 in. its bore will control the quantity of gas admitted to: the chamber 28 and a like movement of the; stem 33 will control the quantity of steam admitted to such chamber.

. \Vhat we claim; as new and desire to secure by Letters Patent is-:

1'. In a burner of' the character described,

Contes of? this: patient may be obtainedv for the combination with a burner casing, of a boiler associated therewith, a source of liquid fuel, a fuel feed conduit connected with said source and having a portion thereof encircling said burner whereby the fuel passing through said conduit is converted into gas, a steam conduit connected tosaid boiler, a mixing valve into which both of said conduits discharge and wherein gas and steam are admixed,-and a conduit leading from the discharge end of said valve to said burner casing.

2. In a burner of the character described, the combination with a burner casing, of a boiler supported thereby, a liquid fuel tank, a feed pipe leading from said tank and having a portion thereof encircling said burner, a steam pipe leading from said boiler, a mixing valve into which both of said pipes dis charge, and a pipe leading from the discharge end of said valve to said burner casing.

3. In. a burner of the character described, the combination with a burner casing having. a series of flame-outlet orifices in its wall, of a boiler supportedpn said casing, a liquid fuel tank, a pipe leading from said liquid fuel tank and having a portion thereof encircling said burner casing in line with the orifices therein, a steam pipe leading from said boiler, a valve having separate nipples to which the discharge ends of said pipes are respectively connected, said valve having a mixing chamber into which gas and steam are discharged through separate conduits from said pipes, and a pipe leading from the discharge end of said valve to the 7 bottom of said burner casing.

In testimony whereof we have aflixed our signatures in presence of two witnesses.
